Applioationfiled July 23, 1900. Serial No.'24,602. (No specimens.)

To all "whom, it may concerm Be it known that I, HEINRICH GB'ETH, merchant, a subject of the King of Prussia, Emperor of Germany, residing at Plettenberg, in the Kingdom of Prussia and Empire of Ger-' many, have invented certain new and useful Improvements in Apparatus for the Production of Crinkled Paper, of which. the following is a full, clear, and exact .description.

Apparatus for producing crinkled paper, in connection with which a scraper is used, which strikes against the drying-cylinder over which the paper to be crinkled passes,

are already known. Up to the present, how- 15 ever, it has not been proposed to produce a pattern in which the paper is crinkled with fine'and with coarse streaks, and this efiect is produced by the present invention.

The annexed drawings show one mode of carrying out my invention. V

In the drawings, Figure 1 isa cross-section through the papercarrying cylinders and scraper and drying apparatus. Fig. 2 is a view from below of the scraper and paper to be crinkled and heating-pipes. Referring to the drawings, it will be seen that the scraper d is not smooth on its outting-surface, as is the case of those hitherto in use, but is provided with indentations and protuberances, the efiect of which is that the paperis crinkled in fine and coarse streaks. r

' The action of the apparatus, as illustrated in the drawings, is'as follows: The paperais guided under the cylinder b and whereby it is pressed against the drying cylinder 0. This latter cylinder carries the'paper with it and partly dries it. The scraper dis inclined at an angle of about thirty degrees with the cylinder 0. The scraper d. takes the paper a 011' the cylinder in the usual ma'nnerfindthereby produces the crinkling of same, and, as will be seen from Fig. 2, is provided with indentations at its cutting-face, so that streaked patterns are formed in the crinkling. The paper, which atthis state is not yet per- What I claim, and desire to secure by Let-' ters Patent, is

fectly dried, is carried over the scraper d and guided over the heating-cover f. By so dry In apparatus for the production of crinkled paper, the arrangement of indentations on the cutting-face of the scraper whereby a streaked pattern is produced in the crinkling, substaut-ially'as described.
